I'm getting closer, now with SMTP permitted to whole of Internet to connect to my SMTP/postfix server & for my postfix server to connect out to public Internet on tcp 25 as well.
I send emails from permitted domain's SMTP servers with "Receipt Acknowledgemt" & the ack returned said it was delivered but somehow there's no mail in the mailbox & using the site below to test, it gave Rejected :
http://legacy.zoneedit.com/whois.html
OK, connected to gate1.mds.com.sg... < 220 gate1.mds.com.sg ESMTP
HELO edit.dnsvr.com < 250 gate1.mds.com.sg MAIL FROM:sender_id@mds.com.sg < 250 sender sender_id@mds.com.sg ok RCPT TO:recipient_id@myportaltech.com < 550 #5.1.0 Address rejected.
The recipient_id is basically a Linux OS id in my SMTP server. Would this work or I'll need to have virtual domain ids ?
